IMPROVEMENT' IN FAsTENERs FoR SPINNING-RINGS;

Specification forming part of Letters Patent No. 112,655, dated March14, 1871.

` `To all persons to whom', these presents may come Be it known that I,CHARLES EDWARD A -TROWBRIDGE, of Whitinsville, in the county 1 1 ofWorcester and State of Massachusetts, have 3 l made a new and usefulinvention having referp ence to Rin g and Traveler Spinning-Frames;

and do hereby declarethe same to be fully specification and panyingdrawing, of

frame7 or machine.

rljhe nature of such invention or improvement, as it may be termed,consists in the ar rangement of a spring-catch or ring-fastener on theunder side of the ring-rail, so as, when Ai l in engagement with the rmg, 4to extend up l within tlieopening of the ring-rail and catch y l ortake upon the inner flange of the lower race 3 of the ring, when suchring may be a duplexrace ring, or in a rabbet or notch in the ring,

Q, when what is termed a single-race ring/in i order to hold or aid inholding the .ring in `Aplace on the rail or in the circular rabbet or l3" socket for the reception of such ring.

In order to hold the duplex-race ring in its A Ay socket it has beencustomaryheretofore to ac- 3 @complish the same by means of one or moreA screws, or such and washers arranged on the jupper" surface of therail, and `so as to lap on or over the outer lian'ge of the lower raceof the ring.

A vices, arranged on the A grail and extended above. such, fllamentsareliable to gather and impede the traveler close to and On such holdingdeupper surface of the `while in operation. Besides, they` are obstathetop of the rail in order to cleanse it of oil or dust.

It will readily be seen that by arranging the A `ring-fasteningunderneath the ring-rail, and l gso constructing and applying suchfastening y that it may be caused to catch or take upon the inner angeof the lower race of the duplexl lrace ring, all danger of collectinglaments `lyon the fastener, and thc'evil consequences of the rail, as insuch case the fastener will take or catch upon the circular shoulder orrabbet usually below the inner iiange of the race. When applied to ashanked ring the improvement saves the necessity of one or moreclamp-screws inserted horizontally in the rail for the purpose ofholding the ring in place in its socket. It also saves the necessity ofsplitting the eccentric annular carrier of the ring, in order to effect,by means of a clamp-Screw, the retraction of it and the ring lin placein the socket of the ring-rai1.

In the drawing, A denotes the ring-rail as provided with duplex-racerings B' B', resting in sockets or circular rabbets a a', made in thetop of the rail and around the spindle-open` ings b b', which go downthrough the rail.

vEach duplex-race ring has two annular races,

c d, united by a connection, e.

The ring-fastener is shown at C as arranged between the two openings bb, and underneath the rail or its top part f. Such ring-fastener, asshown, is constructed as an elastic spring latch to extend v'up withinthe opening of the rail and take or catch upon the inner iiange of thelower race of the ring.

' TheV fastener may be fixed to the rail by a A ring, should hold it inplace in its socket with sufficient tenacity or power 'to preventdisfastener to catch or take upon the inner ange placement of itwhile-the traveler may be in of the lower race of the ring, or upon ashouloperation. der or its equivalent made in or on the rin g;
